Constitutive relations for the interaction force in multicomponent particulate flows
TL;DR: In this article, the authors give a brief review of the various relations proposed for the interaction force in multiphase (or multicomponent) mixtures and provide an alternative approach for finding the drag force on a particle in a particulate mixture.

A Mixture Theory formulation for hydraulic or pneumatic transport of solid particles
TL;DR: In this paper, the authors discuss the importance of constitutive modeling of the stress tensors in certain engineering issues, related to the pressure drop and skin friction, encountered in solids transport.

A note on the meaning of mixture viscosity using the classical continuum theories of mixtures
TL;DR: In this article, the authors provide a brief review of the basic equations for the flow of two linearly viscous fluids using the mixture theory equations given in Atkin and Craine [R.E. Craine, Continuum theories of mixtures: applications, J. Inst. Math. Appl.
A note on invariance under superposed rigid body motions
A. E. Green,P. M. Naghdi +1 more
TL;DR: In this article, the material response functions, which may be represented as scalars, vectors or tensors, are determined by the use of appropriate invariance requirements under superposed rigid body motions.

Removal of malaria-infected red blood cells using magnetic cell separators: A computational study
TL;DR: This paper model the malaria-infected RBCs (pRBCs) as paramagnetic particles suspended in a Newtonian fluid and shows that in order to achieve a capture efficiency of 99% for the pR BCs it is required to have a longer length than 80 mm; this implies that in principle, using optimization techniques the length could be adjusted, i.e., shortened to achieve 99% capture efficiency.

Equation of motion for a small rigid sphere in a nonuniform flow
Martin R. Maxey,James J. Riley +1 more
TL;DR: In this paper, the forces on a small rigid sphere in a nonuniform flow are considered from first prinicples in order to resolve the errors in Tchen's equation and the subsequent modified versions that have since appeared.
